Thinking about Costcos food? Our Kirkland Natures Domain Salmon and Sweet Potato Dog Food Review helps you decide.

Alright, let's talk about this Kirkland Signature Nature's Domain Salmon and Sweet Potato dog food. My usual brand started getting pricey, plus my older dog seemed a bit itchy, so I figured it was time for a switch.

Went on my regular Costco run, you know how it is. Saw this big yellow bag, salmon formula. Read the ingredients – grain-free, salmon first, sweet potatoes. Sounded decent enough, and the price for that huge bag was hard to beat. So, I heaved it into the cart.

Got it home, opened it up. The kibble size is pretty standard, not too big or small. Didn't have a super strong fishy smell, which was nice. Some fish-based foods can stink up the whole pantry, but this one was okay.

The Switch Over

Now, the important part: getting the dogs onto it. I didn't want any stomach upsets, especially with my older girl. So, I did the usual slow transition.

• Days 1-3: Mixed about 25% new food with 75% old food. Scooped it out, mixed it right in their bowls. They ate it, no hesitation. Good start.
• Days 4-6: Went to about 50/50. Still watching them, checking their... output. Everything seemed normal. No weird reactions.
• Days 7-10: Upped it to 75% new food, 25% old. They were still chowing down happily.
• Day 11 onwards: Fully switched to the Kirkland salmon food.

The whole process took about a week and a half, maybe a little longer. No major digestive drama, which was a relief. Had one day with slightly softer stool, but that cleared up quick, could have been anything really.

Living With It

We've been using this food for a few months now. What have I noticed?

Coat: My older dog's coat actually does seem a bit better. Less flaky skin, maybe a bit shinier? It wasn't a miracle cure for her itchiness, that needed other stuff, but the food certainly didn't make it worse and might have helped a little.

Energy: Energy levels seem about the same. They're active dogs, and they stayed active. No sudden lethargy or crazy bursts of energy.

Digestion: This is the big one for me. Stools are consistently firm and, well, manageable. Less volume than some other foods we've tried. That's always a plus.

Do they like it? Yeah, they eat it right up every meal. No complaints there. They get excited when they hear the scoop hitting the bag.

One funny thing – the bag is huge, obviously, being from Costco. Storing it is a bit of a hassle. I ended up buying a big plastic container with wheels to keep it fresh and easier to handle. Just something to keep in mind if you don't have much storage space.

So, overall? Yeah, I'm sticking with it for now. It does the job, the dogs do well on it, the ingredients seem solid for the price point, and buying it at Costco is convenient enough. It’s not some fancy boutique brand, just straightforward food that works for my dogs and my wallet. Been a pretty practical choice.
